Living matter has adaptive mechanisms as categorized into four, sensory adaption, adaption by learning, physiological adaption, and evolutionary adaption. Learning from these adaptive mechanisms, we are particularly interested in using robots as moving sensor agents, that we call sensor agent robots, to gather information of buildings and resident. The information obtained by the sensor agent robots is used to record life phases of the environment relevant to buildings. We call this concept "biofied building" or "biofication of living spaces" and are working to integrate the concept. We are conducting research activities to realize "biofied building" here at Mita laboratory.
